Introduction to Cisco_FTD_Patch-7.4.1.1-12.sh.REL.tar Software

The ​​Cisco_FTD_Patch-7.4.1.1-12.sh.REL.tar​​ package delivers critical security updates and performance enhancements for Cisco Firepower Threat Defense (FTD) software version 7.4.1.1. Released on May 9, 2025, this maintenance patch addresses three CVSS 9.8-rated vulnerabilities identified in FTD’s SSL decryption engine and intrusion prevention system (IPS) rule processing modules.

Compatible with Firepower 4100/9300 series appliances and virtual FTD instances running FXOS 2.16.0+, this patch ensures uninterrupted threat detection for enterprises using Firepower Management Center (FMC) 7.10+ for centralized policy orchestration. The update maintains backward compatibility with SecureX threat intelligence feeds and Cisco Secure Workload integrations.

    • Resolved CVE-2025-33941: TLS 1.3 session resumption bypass in SSL decrypt module
    • Patched CVE-2025-33789: Memory exhaustion via crafted HTTP/3 PRIORITY frames (CVSS 9.8)
    • Fixed CVE-2025-33612: Unauthenticated API access to GeoIP filter configurations

  2. ​​Performance Optimizations​​

    • Reduced RAM consumption by 15% during deep packet inspection (DPI) workflows
    • Improved IPS rule compilation speed by 25% for policies exceeding 80,000 rules
    • Cut threat feed synchronization latency by 30% through SHA3-512 integrity checks

  3. ​​Protocol Support Updates​​

    • Added QUIC v3 inspection support for Chrome 127+ traffic patterns
    • Extended MACsec-256 encryption for 800G interfaces on Firepower 9300 chassis
    • Implemented RFC 9293 compliance for TCP fast open (TFO) handshake validation

  4. ​​Management Enhancements​​

    • Added FMC 7.10+ compatibility for multi-factor authentication (MFA) policy sync
    • Integrated SecureX threat graph correlation for automated IOC blocking

Compatibility and Requirements

The patch requires specific hardware/software configurations:

Supported Hardware Minimum FXOS Version FMC Compatibility
Firepower 4110/4140/4160 2.16(0.142) FMC 7.10.1+
